Sylvester McCoy credited as playing...
The Doctor
- Group-Captain Gilmore: What am I dealing with? Little green men?
- The Doctor: No, little green blobs in bonded polycarbide armor.
- Ace: [driving the Doctor back to the school] These Dayleks...
- The Doctor: Daleks.
- Ace: Oh, Daleks. Where are they from?
- The Doctor: From Skaro. At least originally. They're the mutated remains of a species called the Kaleds. Left here.
- Ace: When were they left here?
- The Doctor: No! Turn left here.
- Ace: Oh, right.
- The Doctor: No, left! You've missed the turning!
- Ace: What turn, where?
- The Doctor: Why don't you concentrate on where you're going?
- Ace: Well, I'm doing the best I can. If you don't like it, you drive!
- Ace: Professor, I'm hungry! Lack of food makes me hungry, you know.
- The Doctor: Lack of food makes you obstreperous!
- [the doctor is locked in a basement with a Dalek]
- The Doctor: Ace! Ace! Open the door! Ace, open...
- [He turns and sees the Dalek levitating up the stairs towards him]
- Dalek: You are the Doctor! You are the enemy of the Daleks! You will be exterminated. EXTERMINATE! EXTERMINATE! EXTERMINATE! EXTERMINATE! EXTERMINATE!
- Ace: So no more Daleks can be transported through here?
- The Doctor: Well, It'll slow them down a bit, until the operator can repair the systems.
- Ace: The Operator?
- The Doctor: Yes, the Daleks usually leave an operator on station in case of any malfunction.
- Ace: And... that would be another Dalek.
- The Doctor: [realizing] Yes.
- [a Dalek appears]
- Dalek: Stay... where... you... are! Do... not... move!
- The Doctor: Oi, Dalek! It's me, the Doctor! What's the matter, don't you recognise your mortal enemy?
- Group-Captain Gilmore: Doctor, my men have just put three high explosive grenades into a confined area. Nothing even remotely human could have survived that.
- The Seventh Doctor: That's exactly the point, Group-Captain. It isn't EVEN remotely human!
- Ace: What are you expecting to find down here, anyway?
- The Doctor: The unknown.
- Ace: Oh, isn't that a bit dangerous?
- The Doctor: Probably. But then if I knew what was down here, I wouldn't have to look.
- The Doctor: Your species has the most amazing capacity for self-deception, matched only by its ingenuity when trying to destroy itself.
- The Seventh Doctor: [the Doctor is knelt coughing on the ground having blown up a Dalek with some nitro-9 explosive. The fuse had a shorter time on it than Ace told him] Ace! You said ten seconds.
- Ace: Nobody's perfect, Professor.
- [referring back to Ace's earlier, rather transparent denial of packing Nitro-9]
- The Seventh Doctor: Ace, give me some of that Nitro-9 that you're not carrying. Quickly!
